Answer:
Step-by-step explanation:
First we have to assume the smallest integer.
Let,
the smallest integer is x
So, the other two integers are-
x+1 and x+2
Now,
the sum of these 3 integers is greater than smallest integer by 11
So, we get
x+(x+1)+(x+2) =x+11
This is the required equation.

Step-by-step explanation:
You will need this formula:
Years = ln (Total / Principal) / rate
(where "ln" means natural logarithm)

Years = ln (200 / 100) / rate
Years = 0.69314718056 / .052
Years =
